The dog's thrusts grow more ferocious as he nears his climax, his powerful hind legs shaking violently beneath him. His hot breath fans across your neck and shoulders, his rough tongue flicking out to taste the sweat that coats your skin. With a final, desperate cry, he releases himself into you, filling your ass with his warm seed as he unleashes all of his pent-up desire in one incredible burst.

The dog shudders and growls low in his throat as he pumps his seed deep into you, marking you as his own. His knot retracts slowly from your ass, giving a final hard thrust before finally pulling free. He collapses on top of you, his heavy breath warm against your neck as he pants softly.

Pushing forward with renewed vigor, Dogmeat takes the sanghellie roughly, his powerful hind legs driving into the alien's body as he buries himself as deep as possible. He growls low in his throat, his excitement and arousal fueling each thrust that connects them closer together. The feel of the other male beneath him only serves to heighten Dogmeat's pleasure.

Unfazed by the size of the sanghellie's ass, Dogmeat continues his relentless pace, grunting and growling as he takes the other male roughly. The tightness and heat surrounding his shaft only serve to increase his excitement, driving him deeper with each powerful thrust. He doesn't care about hurting the sanghellie; all that matters is the satisfaction of their bodies joining together in this primal act.

Time seems to stand still as Dogmeat takes you roughly, using your mouth as his personal pleasure tool. His cock throbs inside you, pre-cum spilling down your chin and dripping onto the ground. He growls louder still, unable to contain himself as he feels the inevitable release building deep within him.

With a final, powerful thrust, Dogmeat's body tenses and he cries out in ecstasy as his seed erupts from his cock, filling your mouth with hot, salty cum.

As you feel the knot begin to shrink back down, Dogmeat pulls free of your mouth and collapses onto his side, panting heavily. He looks up at you through half-lidded eyes, a satisfied grin spread across his muzzle. "That... was incredible," he gasps out between breaths.

His cock continues to twitch and throb with aftershocks of pleasure as he catches his breath, the knot now flattened against his skin where it had been moments ago.
